Specification of I.etters atent. A .Patented Oct. 3, 1916.

Application filed September 18, 1915. Serial No. 51,386. i

To all whom t may concern Be it known that we, VFRANK IHRCKE and HERMAN J. BRENNEGKE, citizens ofV the United States, residing at Chicago, inthe 5 county of Cook and State of Illinois.L have invented certain new and useful- Improvements in Flexible Goggles, of which the folafter described in detail, illustrated inthe accompanying drawing, and incorporatedin the appended claims.

Lens-connections, with or without separate nose-contactingl portions and with or without substantial flexibility, have formed the subject-matter of numerous inventions or improvements, many of which have failed to prove commercially or practically useful by reason of prohibitive cost, complicated construction, or ungainly appearance.

In the present invention the lflexibility which tends to support lenses ,in that normal relative relation describedin Patent No.

. 1,118,631, is combined with the well known and simple form of rigid lens-connecting nose-piece, and is an improvement upon said patent in so far as it eliminates the practical individuality of the bridge as distinguished y from the nose-bow or "nose-contacting por- 4o tion as a separate member.

In the present invention the continuously restrained, or substantially'stopped, angular movement of the lenses provided forl In Patent No. 1,118,631, is tion of the hinge connection involving the objectionable dead stops which formed the i subject-matter of Reissue Patent No. 13,231.

The old, simple form of nose-contacting bridge, or nose-piece lens-connection, is also retained, by combiningtherewith the substantially resisting flexibility of said Patent No. 1,118,631. In the present improvement said substantially iniexible nose-piece and iieXible lense-connection are combined-,in a;

single member, which to all appearances is merely a nose-contacting bridge, by provid- 'ing the ends of the latter with flexible por` tions which are secured to the lenses.

Our Improvements further contemplateV the combination of the combined iieXible and rigid nose-contacting bridgewith the flexible connection of Patent No. 1,118,631 minus the nose-piece, and will l'be more readily understood by reference to the accompanying drawing, in which- Figure 1 is a front view of a pairr of goggles embodying our invention. Fig. 2 is an enlarged top plan view of the lens-connections, the lenses being partly broken away. Fig. 3 illustrates the parts in Fig. -2 with 70 the lenses moved angularly toward each lother rearwardly. Fig. 4 is a similar view with the lenses moved forwardly. Fig. 5vis a rear viewof Fig. l with the lenses partly broken away. l v 75 In the several views 2' and 3 represent a pair of rimlessY lenses provided with usual temples 4 and 5 mounted on the lenses in any suitable manner.

6 represents a nose-bow, 11ose-p1ece,or 80 nose-contacting portion rounded In cross 'section of conventional arched or curved form, as shown. This nose-piece has spring ends 7 and 8 made of any suitable material having suflicient body` and elasticity to normally hold'the lensesl in their proper` relativel relation while permitting relative angular movement thereof as in the case of any of the numerous well known forms of merely iieXible connections. In the present instance the ieXible ends 7 and 8 are shown as separate members having inwardly bent lugs or portions 9 and 10 which engage slots or recesses 1l and 12 formed in the ends of the member 6 which is of rounded cross sec- 95 v tional form and made of onyx, glass, cellu- 10 to the nose-piece 6, though these details maybe varied in any suitable manner-without departing from the spirit-of ourinvention. The opposite ends lof the members .7 and 8 are bent outwardlyfrom each other to form lens-contacting portions 15 and 16 which are secured to the lenses by means of'llO screws or rivets 17. The ends or lugs 15 and 16 are placed against the front sides of the against movements pivotally on the screws or rivets. Hence the nose-piece alone with its flexible'ends and with the aid of one screw or rivet at each end is capable of supporting therlenses in their proper relation. Similar shoulders formed by similar bendings of the auxiliary bridge 18 lend similar support. By making use of the two bridges, or the combination nose-piece and bridge and auxiliary bridge or connection, and attaching the ends of the respective bridges to the opposite faces of the lenses a very stable relative support is lent the lenses and the resistance to flexibility in each bridge need not be more than half as much as where a single bridge is employed with a consequent lessen ing of strain in the parts of the lenses in which the screws or rivets are inserted.y

It will be noticed by reference to Figs. 3 and l that although the bridges or connections are attached to opposite faces of the lenses their flexings do not counteract each other and the lenses may be folded upon each other and contained in a small case.

The nose-piece being a separate member may be conveniently given sufficient body t-o make it comfortable and it is not dependent Aupon the material used to gain the connective flexibility between its ends and the lenses, but may be of whatever different material which novelty and pleasing appearance may suggest. lVhile this double bridge connection is very simple in construction the Copies of this patent may be obtained for lenses, respectively,

shoulders opposite the adjacent edges of the lenses coupled with the attachment to both the opposite faces of the lenses make the connection very firmagainst movements on the rivet-s or accidental movements of the lenses relative to each other.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination with a pair of lenses, of an upper flexible bridge connecting said lenses, a comparatively inflexible nose-piece arranged below said bridge, and flexible connectors attached to said nose piece and and bridging the space between the ends of the nose piece and the lenses.

2. The combination with a pair of lenses, of an upper flexible bridge arranged forwardly of the rear faces of the lenses and having ends which are attached to the rear faces of the lenses, a nose-piece below said bridge rearwardly of the vertical plane of said bridge, and flexible connections between the ends of said nose-piece and said lenses, said flexible connections being secured to the front faces of the lenses.

.3. The combination with a pair of lenses, of an upper and a lower bridge connecting said lenses, each of the ends of each of the said bridges bent twice at right angles to .form shoulders opposite the adjacent edges of the lenses, one of said bridges being attached to the forward faces of the lenses while the other is attached to the rear faces of the lenses, one of said bridges being a continuously flexible member and the other having an inliexibleand curved middle portion which serves as a nose-piece and flexible end portions.

In testimony whereof we have hereunto signed our names.
